The surface structural phase changes by continuous electron beam impact on construction steel 12X18H10T were studied in this paper. As a generator of plasma-beam discharge was used device tokamak. The main objective of the work on the simulation bench was to obtain data on the structural materials samples' surface degradation degree under the influence of exposure to the electron beam and plasma discharge. Scanning electron microscope was used to study the surface morphology after continuous electron beam impact of the steel. As the matter of fact, the energy of electrons was quite low (less than 5 keV), consequently radiation defects were not formed and the entire beam energy went into heating of the target. The built-in modules of transient thermal and steady-state thermal temperature were found to be used numerically as the solution of the problem connecting with arbitrary geometry samples.
